Electrical cooking appliance with automatic cleaning of cooking chamber

An electrical cooking appliance with automatic cleaning of a cooking chamber, the appliance comprising:

• a steam supply device configured to generate steam and supply the steam to the cooking chamber;
• a water supply pump that supplies water from a water tank to the steam supply device;
• a water discharge pump that collects condensed water from the steam supply device into the water tank;
• a water-level sensor configured to detect a water-level in the steam supply device;
• and
• a controller configured to activate the water supply pump to supply water to the cooking chamber and activate the steam supply device to supply steam to the cooking chamber to clean the cooking chamber based on a detection result of the water-level sensor, wherein the steam supply device includes a steam supply configured to generate steam and supply the steam to the cooking chamber through a steam supply channel, wherein the water-level sensor is configured to detect a water-level of the steam supply based on a water-level using a low water-level sensor and a high water-level sensor, and wherein the controller is further configured to:
• when the high water-level is detected by the high water-level sensor of the water-level sensor, continue to activate the steam supply and the water supply pump for a first predefined duration from a time when the water-level is detected by the high water-level sensor, such that water is supplied and filled onto an inner bottom face of the cooking chamber.

An electrical cooking appliance with automatic cleaning of a cooking chamber, the appliance comprising:

• a steam supply device configured to generate steam and supply the steam to the cooking chamber;
• a fluid supply pump that supplies fluid from a fluid tank to the steam supply device;
• a fluid discharge pump that collects condensed fluid from the steam supply device into the fluid tank;
• a fluid-level sensor configured to detect a fluid-level in the steam supply device;
• and
• a controller configured to activate the fluid supply pump to supply fluid to the cooking chamber and activate the steam supply device to supply steam to the cooking chamber to clean the cooking chamber based on a detection result of the fluid-level sensor, wherein the steam supply device includes a steam supply configured to generate steam and supply the steam to the cooking chamber through a steam supply channel, wherein the fluid-level sensor is configured to detect a fluid-level of the steam supply based on a fluid-level using a low fluid-level sensor and a high fluid-level sensor, and wherein the controller is further configured to:
• when the high fluid-level is detected by the high fluid-level sensor of the fluid-level sensor, continue to activate the steam supply and the fluid supply pump for a first predefined duration from a time when the fluid-level is detected by the high fluid-level sensor, such that fluid is supplied and filled onto an inner bottom face of the cooking chamber.
